A long-standing question in biology is how a group of primordial cells can give rise to complex organs. A new study finds that, in an ancient land plant, growth rate variation patterned by meristematic cells primarily determines shape.
生物学中长期存在的一个问题是，一组原始细胞如何能产生复杂的器官。一项新的研究发现，在一种古老的陆地植物中，由分生细胞决定的生长速度变化模式主要决定了植物的形状。
